Launch the “XPi Installer.app” and choose “Open” the first time to confirm that you want to use the application.

Select your desired “SD Card” from the available devices listed in the center of the application. It won’t necessary be named anything to do with what it is.

ress the “Install Raspbmc” button and answer “Yes” when prompted to continue the process.

Wait a few minutes for the installation files to transfer. You’ll now when it’s complete because it will eject the SD Card from your computer and the progress bar will stop moving, and it’ll display the text “Success!” at the bottom.

Remove SD Card from your Mac.

Insert SD Card into your Raspberry Pi and connect it to your television as well as to your Internet connection by ethernet, electricity, and wireless mouse.

Follow the on screen prompts to complete installation.

Connecting Everthing UP.

Monitor Source

To connect the pi to your monitor, you will will need the HDMI cord which be inputed into the monitor or any other capable video source.

Its Ethernet

Now, you gonna want to connect the pie to your internet connection, through the ethernet cord, which you will have to hook up to your rootor.

Mice and Keyboard to Power

ok, now just plug your keyboard and mice into the usb ports and you will now have to get the micro usb adapter to give it power which i mentioned earlier.

Tweak Those Settings!

Once your Raspberry Pi boots for the first time you'll need to follow the screen prompts which will lead you to the completion.

Now the best settings I found out there is to set the:

Resolution, you this found under Settings > System > Video Output. If you're only going to be watching 720p videos, you should change this to 720p. It should help the system and menus feel a little snappier.P

Overscan, found under Settings > System > Video Output > Video Calibration. If you find that the XBMC interface stretches beyond the edges of your TV screen, you'll want to calibrate your video using this wizard to fix it.P

System Performance Profile, under Programs > Raspbmc Settings > System Configuration. This is a Raspberry Pi-specific setting that basically allows you to overclock the device, making everything run a little bit faster and a little bit smoother. I recommend trying the "Fast" setting, which will speed everything up without sacrificing stability. The "Super" setting will be significantly faster still, introduces the possibility of instability (Update: it does not void your warranty as previously stated; your warranty will stay intactat high overclocking levels). You can also perform more advanced overclocking tweaks if you're familiar with overclocking.P

MPEG2 Codec License, which you'll need to buy from the Raspberry Pi store and enable under Programs > Raspbmc Settings > System Configuration. This allows you to play MPEG-2 videos, which the Pi cannot play out of the box. If you don't have any MPEG-2 Videos, you can skip this.P
